Patent WO-0181912-A1 (WO)
Inventor: LIPINSKI JUERGEN
IPC: G01N1/34
Filed: 2000-04-27
Abstract: Für die chemisch analytische Untersuchung von flüssigen und gasförmigen Proben ist die Solid Phase Microextraction (SPME) die bedeutendste Mikroextraktionstechnik. Die Menge der dabei extrahierten organischen Substanzen ist jedoch limitiert. Die benötigten Extraktionszeiten sind lang und der fragile Fiber ist mechanisch nicht belastbar. Die neue Metallkanüle ermöglicht eine dynamische Extraktion. Die Extraktionsausbeuten sind höher bei gleichzeitig kürzeren Extraktionszeiten und hoher mechanischer Stabilität der Extraktionskanüle. Die innere Oberfläche der Kanüle ist ganz oder teilweise mit einer Polymerschicht belegt. Die Probe wird wiederholt mit hoher Geschwindigkeit durch die Kanüle gedrückt oder gesaugt. Dabei reichern sich die organischen Substanzen der Probenmatrix in der Polymerschicht an. Das Volumen der Polymerschicht bestimmt die maximal extrahierbare Menge und ist im Vergleich zur SPME bedeutend größer. Die Geometrie der Kanüle gewährleistet kurze Diffusionswege und damit kurze Extraktionszeiten. Die Metallkanüle kann mit einem Kunststoffkopf versehen und auf den Glaskörper einer Spritze aufgesetzt werden. Der Spritzenkörper wird zusätzlich mit einem Einlass für ein Spülgas ausgestattet, um so bei der thermischen Desorption die extrahierten Substanzen in Richtung Kanülenspitze aus der Kanüle herauszuspülen.
